富氢盐水对高压电烧伤大鼠肠系膜微血管白细胞流变行为的影响

摘要

目的 探讨富氢盐水对高压电烧伤大鼠肠系膜微血管白细胞流变行为的影响.方法 将180只SD大鼠随机分为高压电烧伤实验组、高压力烧伤富氢盐水治疗组、假高压电烧伤组,高压电烧伤罂粟碱治疗组.在伤后不同时间点,各组大鼠腹腔分别注射0.9%氯化钠注射液、富氢盐水、0.9%氯化钠注射液、罂粟碱.比较伤前及伤后各时相大鼠肠系膜微血管白细胞流变行为变化情况.结果 假高压电烧伤组于观察的各个时相的肠系膜微血管白细胞流变行为均无明显变化,比较差异无统计学意义(P>0.05).高压电烧伤实验组大鼠伤后各时相滚动白细胞数、白细胞黏附数、白细胞-内皮细胞接触时长均高于伤前15 min,比较差异有统计学意义(P<0.05);白细胞滚动速度则低于伤前,比较差异有统计学意义(P<0.05).高压力烧伤富氢盐水治疗组与高压电烧伤罂粟碱治疗组伤后各时相滚动白细胞数、白细胞黏附数、白细胞-内皮细胞接触时长均高于伤前15 m in,比较差异有统计学意义(P<0.05),但与高压电烧伤实验组相比,增长幅度较低;白细胞滚动速度则低于伤前,比较差异有统计学意义(P<0.05),与高压电烧伤实验组相比,降低幅度较低.结论 富氢盐水可有效减轻由于高压电烧伤造成的大鼠肠系膜微血管白细胞流变行为的改变,对大鼠肠系膜具有一定保护作用.%Objective To investigate the therapeutic effect of hydrogen-rich saline on the rheological behavior of leukocytes in mesentery capillary of rats with high-voltage electrical burn .Methods 180 rats were randomly divided into four groups :burn injury plus normal saline group ,burn injury plus hydrogen-rich saline group ,sham plus normal saline group ,and burn injury plus papaver-ine group .The rats were received saline ,hydrogen-rich saline ,saline ,papaverine at different time points after scald respectively .The changes of rheological behavior of leukocytes in mesentery capillary of rats before and after the injury were investigated .Results The rheological behavior of leukocytes in mesentery capillary of the control group were observed no significant change (P>0 .05) . In experimental group the rolling white blood cell count ,the number of leukocyte adhesion ,the length of contact of leukocyte-endo-thelial cell at each phase after injury were higher than those at 15 min before injury (P<0 .05);leukocyte rolling speed after injury is lower than that before injury (P<0 .05) .In treatment group and positive control group ,the rolling white blood cell count ,the number of leukocyte adhesion ,the length of contact of leukocyte-endothelial cell at each phase after injury were higher than those at 15 min before injury (P<0 .05) ,but compared with the experimental group ,the increase range was lower (P<0 .05) .leukocyte rolling speed after injury is lower than that before injury (P<0 .05) ,and compared with the experimental group ,the reduction was lower (P<0 .05) .Conclusion The hydrogen-rich brine can effectively reduce the changes of rheological behavior of leukocytes in mesentery capillary of rats caused by high-voltage electrical burn ,and have a protective effect on rat mesenteric .
